A framework I is provided which may be common to the feeding mechanismused in conjunction with my can wrapping and labeling machine,

such feeding mechanism being omitted from the drawings. The framework Iincludes side members Ia which support therebetween a table 2. At oneside of the table, midway between the side members Ia, there is provideda can receiving frame 3, which may be formed integral with the table 2.The can receiving frame 3 projects above the normal level of the table 2and is provided with a centrally disposed oval shaped recess 3a,disposed with its longest axis lengthwise with the machine, that isparallel to the side members Ia. One entire longer side of the recess 3ais cut away so as to form a gateway 3b intersecting a side of the canreceiving frame 3. The gateway extends below the normal bottom of therecess 3a and is adapted to receive a gate member 4. The gate member 4is complementary to the oval recess 3a, that is its inner side issemi-oval and when the gate is in its upper position entirely closes thegateway 3b. The gate member 4 shifts from a position below the normalbottom designated 3c of the can receiving recess to a position in whichthe upper side of the gate is flush with the top of the can receivingframe as shown in Figs. 3 and 5. A centrally disposed operating rod 5extends downwardly from the gate 4 through a suitable guide 211.depending from the table 2 and terminates in a bearing which supports acam follower 6. The cam follower operates in a cam channel formed in agate operating cam I. The cam I is mounted on a cam shaft 8 which isdriven by any suitable means not shown and is disposed transversely withthe framework so as to extend underneath the can receiving frame 3.

The oval-shaped bottom portion 30 of the can receiving frame is in turnprovided with an ovalshaped recess in which is mounted the flat head ofa bottom plunger 9, as shown in Figs. 5, 6 and 9. The can receivingframe or the table supports a guide 21) mounted below and in centeredrelation to the bottom plunger so as to receive a depending operatingrod II], which extends downwardly beyond the guide 22) and is providedwith a bearing for supporting a cam rider wheel II, adapted to operatein a groove or channel formed in a bottom plunger operating cam I2mounted on the cam shaft 8.

A bracket 20 extends laterally from the guide 21) and is adapted tohinge a cam ejector lever I3. The lever i3 comprises an outwardlyextending portion I30. terminating in an arcuate arm portion I3b havinga curvature concentric with the axis of rotation of the lever. Theextremity of the curved arm I3b is provided with a cross member I3ewhich fits in and conforms with a slot 3d formed in the sidewall of therecess 3a opposite from the gateway 3b as shown best in Fig. 9. Theejector lever normally occupies a position in which the cross portionI30 is substantially flush with the sidewall of the recess 3a as shownin Fig. 5. The ejector lever is provided with an arm I3e which extendsoutwardly and downwardly from the bracket 2c and is provided with a camrider I4. The cam rider I4 rides upon an ejector operating cam I5 whichmay be formed integrally with the bottom plunger cam I 2. The ejectoroperating cam I5 in such a case is formed onthe opposite side of the camI2 from its channel as shown best in Fig. 5 and is in the form ofannular track the surface of which extends radially with respect to theaxis of the ejector lever at the portion engaged by the cam rider I4. Asubstantially axially extending boss I5a acts to shift the ejector leverto the dotted line position shown in Fig. 5. The ejector lever is heldagainst its cam by means of a coil spring I6, which may be associatedwith the bracket 20, as shown best in Fig. 7.

The marginal portions of the can receiving frame 3 surrounding therecess 3a, as well as the top of the gate 4, is covered by wrappermargin folding plates I! and I8, and I9. The plates I1 and I8 arepositioned adjacent the can receiving frame 3 and are hinged together attheir one ends by means of a swivel bracket 2|. These plates are similarin form and are adapted to extend from their connected ends aroundopposite sides of the recess 3a, their inner edges designated Ma andI8a. being curved to approximate the form of the recess 3a. Theextremities of the plates I1 and I8 are provided with angularly disposedslots Nb and I8b, through which extend guide pins 20, fastened into thecan receiving frame 3. The slots I11) and l8b are so arranged that whenthe secured ends of the plates I1 and I8 are shifted toward the recess30., the extended ends of said plates move toward each other so that thecurved inner margins Fla and 18a of the plates overlap the margins ofthe. recess 3a as shown in Figs.

1, 5 and 6.

The plate I9 fits on top of the plates I1 and I8 and is substantiallyco-extensive with the top of the can receiving frame 3. The plate I9 isprovided with an oval-shaped aperture I9a which is somewhat larger thanthe recess 3a, so that when the plate I9 is centered with respect to therecess, the margins thereof are exposed as shown in Fig. 2. The plate I9is provided with slots I9b at one end and a slot I at its opposite enddisposed parallel with the longer axis of the recess 3a. The slots I 9breceive the guide pins 20 while the slot I90 receives the shank of theswivel bracket 2|. The latter slot is of sufficient length to permit therelative movements of the several plates. The end of the plate I9 havingthe pair of slots I9b is provided with a depending bracket 22,corresponding to the swivel bracket 2|. The two brackets are connectedto corresponding ends of a pair of levers 23, as shown best in Fig. 6.The levers 23 are L-shaped and are journaled intermediate their endsfrom lugs 3e, extending outwardly and downwardly from the can receivingframe 3. The remaining legs, designated 23a, of the levers 23 extendtoward each other and are joined to a connecting bar. 24a of anoperating member 24. The connecting bar 24a passes around the guide 2band one end thereof is provided with a depending rod 24b, which extendsdownwardly through a guide 2d supported from the side of the guide 2b.

ward each other by action of the levers 23,.they

together delineate an oval-shaped aperture which is centered withrespect to the depression or recess 3a but which is less in diameter.

Mounted above the recess 3a and in centered relation therewith is anupper plunger 2'I, which conforms in shape to but is slightly smallerthan said recess. A longitudinal slot 21a is formed in the plunger 21which receives a bar 28a forming a part of a label retaining means 28.Guide pins 28b extend upwardly from thebar thru the plunger, and aresecured to a cross plate 280 which is provided with a centered opening.boss 21b of the plunger extends upwardly through the cross plate 280. Aguide rod 30 is secured in the boss and secures a collar 30a to theupper end of the boss, said collar is provided with a pair ofdiagrammatically disposed journal lugs 30b, one of which isengageable bya catch lug 28d pivotally supported from the plate 280. A spring 28ctends to force the catch into engagement with its pin, such connectionbeing made when the bar is in its retracted position. Another spring 28extending between the collar 30a and'cross plate 280 tends to force thebar to an extended position. A yieldable cover 29, preferably formed ofrubber covers the bottom face of the plunger 21 and bar 28a.

The rod 30 extends upwardly and through a guide Ib which is supported ona cross member to forming a part of the framework I. The guide lbcarries a lug Id. The catch 28d has an arm 28g. The lug and arm engagewhen the plunger reaches its extreme upper portion to release the catch28d. 7 p

The journal pins 2'Ie fit in slots provided in a yoke 3 Ia mounted atthe extremity of a lever 3|. The lever 3| extends upwardly and away fromthe rod 30 and is journaled on a shaft 32 supported from the frameworkI. The other or remaining arm 3Ib of the lever 3| continues from theshaft 32 and is connected to the upper end of a connecting means 33.

The connecting means includes a rod 33a which extends downwardly througha' guide 34 supported from the framework I. The rod 33a terminates in asocket 332) into which fits a secnd rod 33c. The rod 330 and socket 331)are limited in their relative axial movement by means of a slot and pinarrangement 33d. Shoulders are provided on the rods 33a and 33e, betweenwhich is disposed a stiff spring 33e of greater strength than the spring28f between the retaining means 28 and the upper plunger 21. The lowerend of the rod 330 is connected to one arm of a lever 35 which isjournaled intermediate its ends upon a shaft 36 also supported from theframework I in any suitable manner not shown. The remaining arm of thelever 35 is provided at its extremities with a cam rider 31 which isadapted to fit in a'suitably formed channel provided in the side of acam 38 mounted on the shaft 8. The arm 3Ia of the lever 3| is preferablyoffset laterally with respect to the other arm of said lever in as muchas the cam28 is offset laterally with respect to the axis of the upperplunger.

The main or cam shaft 8 drives a countershaft 39 by means of a chainandsprocket means 40.

The countershaft 39 is hung from the table 2 by means of bracket bearing4|, and supports a centrally positioned segmental spur gear 42.

Above the segmental spur gear 42, the table 2 is raised forming aplatform 2e which is centered with respect to the can receiving frameand extends outwardly'at one end thereof. The

platform 2e is provided with a slot 2f which continues to the canreceiving frame 3 so that the bracket 22 and its lever may extenddownwardly therethrough as shown in Fig. 6.

The slot 2f is adapted to receive a pinion gear 43 which is adapted toengage the teeth of the segmental spur gear 42. The pinion gear 43 iskeyed on a shaft 44 which extends across the platform 26 in bearings 2gformed therein over which are the bearing caps 45. The extremities ofthe shaft 44 protrude slightly beyond the platform 2e at both ends andare joined at the opposite ends by hinges 460. to arms 46b of labelcarriers 46 of which there are two oppositely disposed. Each labelcarrier 46 is provided at the extremity of its arm 46b with a pair ofoppositely disposed label carrying plates 466, shown best in Fig. l ofthe drawings, one extending laterally from the top side of the arm 46band the other extending laterally from the bottom side of said arm 46b.Therefore, there is provided one label carrying plate 460 on each arm46b which cooperate for carrying a label, and the other plate 460cooperates in the opposite direction for carrying a label to the othercan. Each label carrying plate is arcuate in form and of such a size asto fit within and adjacent the margins of the wrapper margin foldingplates, when said plates are in their contracted or inner positions. Theupper plates of the two carriers are complementary and work together toplace a label on each side of the can at the left side of Fig. 1, as doalso the lower plates place a label on each side of the can at the rightside of Fig. 1. During their carrying movement, the arms 46b extend atright angles to the shaft 44 and thereby rotate about a horizontal axisfrom. a position at the side of the platform 2e, remote from the canreceiving frame to a position in which the co-acting pair of plates 46cregister with the aperture 3a. On return movement, the carriers rotateabout a vertical axis; that is in a horizontal plane. In order to guidethe arms 46b in such movement, the bearing caps 45 are provided at theirextremities with upwardly extending guide walls 4511, which coact withguide walls 41a of guide members 41. The guide members .4! are supportedfrom the side members Ia and extend inwardly therefrom over the table 2in spaced relation thereto so that the guide walls 41a form with .theguide walls 450 a pair of slots as shown best in Figs. 1 and 10. Theseslots designated A guide the arms while they rotate about a horizontalaxis. The table 2 at either side of the platform 2c is provided withsemi-circular slightly elevated guide portions 2h, which coact withcorresponding guide portions 411; provided on the under side and. at theextremities of the guide members 41, thus the guide portions 2k and 41bform horizontal guide slots B.

Secured to the under side of the platform 2e on either side of thepinion gear 43 are a pair of brackets 48 which extend downwardly andoutwardly and terminate in upwardly directed spindles 48a, having theiraxes in approximate alinement with the center of movement of the hingemembers 46a. Journaled upon each spindle 48a is a carrier return member49 which comprises an arm 49a terminating in an upwardly directed pin 4%which projects through an arcuate slot 29' on the raised guide portion2h and terminates in a roller 490. The rollers 49c are adapted to engagethe sides of the arms 46b and shift them laterally away from the canreceiving frame in the direction, of the arrows shown in Fig. 1. Thecarrier return members 49 are provided with segmental gear portions 4911which are adapted to engage segmental bevel gears 59 mounted on thecountershaft 39. Springs 5| are provided which connect with the carrierreturn members in such a manner as to return said members to theirstarting position as. soon as the segmental gear portions 49d aredisengaged by the segmental bevel gears 50.

The lowermost label carrying plates 460 of the label carriers engageadhesive supplying rollers 52 during their return movement. The rollers52 are mounted in receptacles 53 which are set into the table 2 shownbest in Fig. 5.

Underneath the position occupied by the lower pair of label carryingplates when the label carriers are in their extreme return position,there is mounted a label support 54, which comprises a platform 54a withupwardly directed guide walls 541) suitably spaced so as to retain astack of labels designated L, as shown in Fig. 3. The support is mountedon a sleeve 55 which extends downwardly through a guide 56 supportedfrom the framework I. A rod 51 extends upwardly into the sleeve 55 andis provided at its lower or protruding end with a roller 59. Between theinner extremity of the rod 51 and the inner end of the sleeve 55, thereis mounted a tension spring 58. The roller 59 engages one end of thelever 60 which is fulcrumed intermediate its end upon the shaft 36. Theremaining arm of the lever 69 is provided with a cam rider 6| whichengages the periphery of a cam 62 mounted on the cam shaft 8, as shownbest in Fig. 4. A spring 63 is disposed between the extremity of the rod51 and the guide 56 and tends to maintain the roller 59 upon the lever60, and consequently holds the rider 6| against the cam 62.

The can and wrapper is delivered to the wrapping and labeling machine bymeans of a carriage or the like such as illustrated in Fig. 8. Thecarriage comprises an oval shaped frame 64, the underside of which isadapted to be coated with an adhesive or to be moistened so as to adhereto adhesive provided around the margins of an oval shaped wrapper W, theadhesive indicated by the character WI. The frame 64 supports a pair ofgripping members 65 which are adapted to engage opposite sides of anoval shaped can designated C; such gripping members being held securelyagainst the sides of the can by means of springs 66. These springssurround shafts extending outwardly from the fingers through suitableguides 64a provided in the frame 64. The frame 64 is provided with arms61 which terminate in wheels 68 or the like adapted to ride upon tracks69 shown fragmentarily in Fig. 1. This construction may be similar tothe feeding arrangement illustrated in my former patent for can wrappingand key placing machine, Patent No. 1,843,458. Of course any othersuitable mechanism capable of supplying the can and wrapper insuperposed centered relation may be used in conjunction with the presentmachine.

Operation of my machine is as follows: A suitable carriage memberdelivers the wrapper with the can thereabove into centered relation withthe recess 3a.the lower plunger 9 and upper plunger 21 are then shiftedtoward the can and wrapper and engage the same. Whereupon the twoplungers move downwardly together pulling the adhesive coated marginalportion WI of the wrapper away -from the carriage. Downward movement ofthe plungers into the recess 3a causes the margins of the wrapper to befolded upwardly as shown in Fig. 12; the upper plunger 21 then movesupwardly until it is clear of the label carriers 46 as shown in Fig. 13.These two members are rotated in a horizontal axis with a pair of thelabel carrying plates in complementary relation and carrying a labeldesignated L. During this movement, the margin folding plates I], I8 andI9, move toward each other so that their inner curved edges engage theprotruding portions of the wrapper and force them inwardly over the topof the can C as shown in Fig. 13, and also indicated in Figs. 5 and 6.The label carriers bring the label into superposed relation with thecan, the label being sufiiciently small in area to fit within theaperture delineated by the plates I'I, I8 and I9 when in their innerpositions. The upper plunger then returns to its lower position shown bydotted lines in Fig. 3, which is similar to the position shown by solidlines in Fig. 5, whereupon the bar 28a presses the central portion ofthe label firmly against the can. This movement of the upper plunger issuch that its marginal portion 21b does not bear against the labelcarrying plate. It should be noted here that the movable bar 28a fitswithin the oval shaped space formed by the complementary pairs of labelcarrying plates. While the label is held by the tension of the bar 28aagainst the can, the carriers are started out on their return movementand therefore pull under the label. As soon as this is accomplished, aslight additional movement of the upper plunger causes the marginalportion 2'") thereof to press firmly against the can, and causing thecatch to lock the bar with retracted position until the plunger is againraised to its extreme upper position. Thereupon the upper plunger againraises part way, as shown in Fig. 14, and at the same time the gate 4moves downwardly. The end of the ejector lever I3 moves inwardly, asshown in Fig. 15 so as to push the can out of the gateway 3b and on to asuitable chute 2k supported from the table 2.

As soon as the ejector lever l3 returns to its position, the bottomplunger 9 is on upward movement and another can and its wrapper isdelivered between the upper and lower plungers.

During the period following the return movement of the label carrier,and before they again start on their operating movement, the labelsupport 54 is shifted upwardly by action of the lever 60 and can 62until the uppermost label engages the lower pair of these plates, beingthe ones in complementary relation. This pair of plates has receivedadhesive, when said plates passed over the adhesive applying roller 52during the return movement of the label carriers. The tension spring 58enables the label support 54 to stop whenever the labels engage thelabel carrying plates. In order to retain these plates in positionagainst the action of the tension spring pressing upwardly thereon,there is provided a pair of levers l0 and H, suitably supported from theframe I in such a manner as to be engaged zy a push rod 12 supportedfrom the lower end of the rod 51 as shown best in Fig. 3. The lever 10is normally held out of the road by means of a spring I3.
